[editar] Stream basada I / O
La corriente a base de entrada / salida de la biblioteca se organiza en torno a la entrada abstracto / dispositivos de salida. Estos dispositivos abstractos permitir el mismo código para manejar la entrada / salida de archivos, secuencias memoria o dispositivos personalizados adaptador que realizan operaciones arbitrarias (compresión, por ejemplo) sobre la marcha .
Original:
The stream-based input/output library is organized around abstract input/output devices. These abstract devices allow the same code to handle input/output to files, memory streams, or custom adaptor devices that perform arbitrary operations (e.g. compression) on the fly.
